As far as I know, even in the New Kingdom era of Ancient Egypt, Egyptians didn't use much of armour. All the reenactments I saw, including the Ex Deo's clip, Egyptians went to battle with their classical dress of fancy "hat" and the "skirt" with a Khopesh and that's it...may Ra recieve our souls.The costume you can find very easely on a costume seller or on Ebay, just search for egyptian costumes.The Khopesh...if you're looking for a cheap one, there's Deepeeka. But also look on the Kult of Athena online store, they might have some great Khopesh for sale.
